SPECIFICATION forming part of Letters Patent lilo. 726,669, dated April28, 1903.

Application filed May 5, 190% Serial No. 105,988; (No model.)

To all whom it may concern.-

- Be it known that I, ZAOHRY 'l. FURBIsH, a

2 is a longitudinal sectional view on the line 2 2, Fig. Fig. 3 is asectional plan view.

Fig. .1: is a detached perspective View, and

Figs. 5 and 6 are views of modifications.

A A are the links of the chain having T- heads 0., preferably rounded,as in Figs. 2 and 4, so as to form a pivot for the link. The body ct ofthe link may be made fiat and solid, as shown, or any shape desired.

B is a connecting member, consisting of two heads D D and asocket-section B, having sockets b bin each side, preferably tapered androunded to fit the heads a of the links. The caps D havefianges d, whichfit over the ends of the sections B and form bearing-flanges for theheads a, of the links.

The caps D are secured to the socket-section B in the presentinstance byriveting the projecting ends I), which pass through openings in theheads, or the caps may be secured to the section by a bolt or othermeans of fastening. V

In assembling the members of the chain one cap can be secured to thesocket of each member B, and then the links A can be fitted to thesockets and the other cap applied and secured. The strain is not takenby the socket'member B but by the links and the caps D. Thisconstruction makes a very flexible chain and one especially adapted to asmall sprocket-wheel. The sockets of the chain can be of any curvature,depending greatly upon the Wheels to which it is to be applied.

In Fig. 5 I have shown a chain made of members including flanged caps inwhich the heads of the links are mounted, and a single piece forretaining each pair of caps in position, substantially as described.

2. The combination of a series of links having T heads at each end andconnecting members, each consisting of a socket-section and two flangedcaps, substantially. as described.

The combination of a series oflinks, having T heads at each end andconnecting members, each member consisting of a socketsection havingtransversely-curved sockets ineach side for the reception of the headsof the links, and flanged caps extending over the socket member andacting as bearings for the links, substantially as described.

4. The combination of a series oflinks, having T-heads at each end andconnecting members, each member consisting of flanged caps and a socketmember having sockets in each side for the heads of the links, andprojections 'at each end passing through the caps, substantially asdescribed. 7
